The utility model discloses a winding device for OCA (optical clear adhesive) production, which structurally comprises a dust removal box, an alignment frame, a base plate and a fixing plate, an electric push rod is used for pushing a lifting plate to enable an air ejector pipe at the lower end to be close to the OCA, so that the surface of the OCA is cleaned in the pulling process, and the OCA is completely removed. Dust on the surface of the OCA optical cement is blown under the action of a suction fan and a fan and is sucked into a filter bag through a suction pipe to be collected, the influence of the dust on the OCA optical cement is avoided, limiting columns can move on the two sides under the action of a twisting nut, the two sides of the OCA optical cement are limited by the limiting columns, and the OCA optical cement is prevented from being damaged. The situation that the OCA optical cement deviates towards the two sides in the winding process is avoided, so that wrinkles in the winding process are reduced, the product quality is better, the winding roller rotates under the action of the second motor so as to wind the OCA optical cement, manual winding is avoided, and the winding efficiency is improved.

The application discloses an interface pretreatment liquid for prelithiation of a positive electrode, a lithium supplementing battery and a preparation method thereof, and relates to the technical field of lithium ion batteries.The interface pretreatment liquid comprises one or more of lithium polysulfide, hydrobromic acid and hydriodic acid as solutes, and comprises 0.1-10% of the solutes and 90-99.9% of solvents in percentage by mass.The solvents are one or more of N-methylpyrrolidone, ethylene carbonate, fluoroethylene carbonate, propylene carbonate, butylene carbonate, dimethyl carbonate, diethyl carbonate, methyl ethyl carbonate, gamma-butyrolactone, methyl formate, ethyl formate, methyl acetate, ethyl acetate, ethyl propionate, propyl propionate, ethyl butyrate, propyl butyrate, dimethyl sulfoxide and dimethyl sulfide.The interface pretreatment liquid has the advantages of simple preparation method, simple use method, short soaking time of lithium supplementing positive electrode sheets in the interface pretreatment liquid, good effect, high production efficiency and suitability for industrial production.

The application discloses a temperature regulating device for low-temperature starting of a fuel cell, which is applied to the field of fuel cells.The temperature regulating device can monitor the water temperature of water entering and leaving the fuel cell and water discharged from a circulating water path in real time through the arrangement of two temperature sensors, and then the water flow can be adjusted according to the water temperature.In the case of low temperature, when the water flow rate is accelerated, the self-diameter ring is powered on, and then the end part of the water guide pipe at the water inlet of the fuel cell is self-expanded in diameter, and then a buffer deceleration layer is formed before the water enters the fuel cell.Compared with the prior art, under the condition of the same water flow rate, the fuel cell can be subjected to smaller impact force, so that the stability of the fuel cell can be greatly improved, the water inlet amount per unit time can be further improved than the prior art when starting at low temperature, the temperature regulating speed of the fuel cell is faster, the effect is better, and the influence of low temperature on the service life of the fuel cell is effectively reduced.

The application provides osmanthus fragrans plant extract mosquito repellent spray with long-acting mosquito repellent and itching, swelling relieving effects and a preparation method thereof, and relates to the technical field of mosquito repellent products. The raw materials of the mosquito repellent spray are as follows: osmanthus fragrans flower extract 7-9 parts, melaleuca alternifolia leaf extract 8-11 parts, chrysanthemum artemisia extract 1-2 parts, radix morindae officinalis extract 12-16 parts, platycodon grandiflorum root powder 16-19 parts, plant essential oil 20-24 parts, glycerol 18-23 parts, sucrose stearate 6-9 parts, p-hydroxyacetophenone 0.2-0.5 parts, stabilizer 3-5 parts and peppermint water 110-120 parts. The mosquito repellent spray can interfere with the activities of mosquitoes to achieve a good mosquito repellent effect, and can form a uniform and stable protective film on the skin surface to prolong the mosquito repellent effect, and can also play a good soothing and skin converging role, reduce local inflammatory reactions, promote skin barrier repair, and effectively relieve itching, swelling and other discomforts caused by mosquito bites.
